The /002 variant of the Audible Driver Module has an opto-isolated Monitor Output
that is open-circuit when the audible is voltage is less than 5V and short-circuit
when the audible output has a voltage present of more than 5V. This allows
independent monitoring of the voltage on the audible output. The Monitor Output
can be wired directly to an input of the I/O card.
